SHEET-DELIVERY M ECH-ANISM.

SPECIFICATION forming lpart of Letters Patent No. 743,393, dated November 3, 1903.

Application filed lune 19, 1902. Serial No. 112,283. (No model.) l

To all whom it may concern:

Be it known that I, ROBERT MIEHLE, a citizen of the United States, residing in Chicago,

' in the county of Cook and State of Illinois,

have invented a new and useful Improvement in Sheet-Delivery Mechanism, of which the following is a specification.

In the patent granted to me September 6, 1898, No. 610,491, I show a cylinder printingpress with both a iiy-delivery acting to deliver the sheet with the printed side down and a sheet-carrier reciprocating to and from the impression-cylinder and delivering the sheet with its printed side up, each delivery being capable of being rendered inoperative when the other is in service. The reciprocating carrier was quite similar in construction to the iiy-frame and consisted of a cross-shaft and fingers attached to and projecting horizontally from the shaft. l

In my present invention I aim to simplify the machine by dispensing with the separate shaft and fingers of the reciprocating carrier by making the fly-frame detachable from the mechanism by which it is oscillated when used as a fly-delivery and attachable to the actuating mechanism of the reciprocating carrier, or, in other words, the actuating mechanisms of both the 'Hy-delivery and the -reciprocating delivery are constructed to permit the ready attachment to them of the ilyframe, which is thus adapted to be used interchangeably with either, serving in connection with one as a iiy and in connection with the other as a reciprocating sheet-carrier. The nature of the changes in construction by which this object is attained are fully set forth below and illustrated in the accompanying drawings, in which latter- Figure 1 is aplan, and Fig. 2 a longitudinal -vertical section, of that portion of a cylinderpress embodying my invention. Fig. 3 shows the ly-frame detached. Figs. 4 and 5 are -sections on the lines 4 4 and 5 5 of Fig. 1, and Fig. 6 is a section on the line 6 6'of Fig. 4.

In said drawings, 10 represents the table .on which the sheets are finally deposited, and

11 11 are the tapes by Which they are brought fromthe cylinder to the delivery apparatus.

5o `The detachable iiy-frame consists of the shaft `plainly shown at Fig. 5.

l l2 and fingers 13 and except in some respects hereinafter pointed out may be of the ordinary construction. It is shown in the drawings connected to the mechanism for operating it as a reciprocating sheet-carrier, and such mechanism will therefore be first described.

14 14 represent bars at each side of the press along which the rollers 15 15 move, and said rollers support carriages 16 and 17, which are reciprocated by cranks 18 on the rock-shaft 19 and links 20, connecting the cranks with the carriages, as shown. One of the carriages has a hub 21, in which is formed a recess for the end of the shaft 12, and the latter is keyed to the hub, as well as confined in it, by a set- Ascrew 22, passing through the side of the hub and entering a side recess in the shaft, as The other carriage also has a horizontal hollow hub 23, which receives a stub 24, held firmly in position by set-screw 25. Shaft 12 at this end is provided with a movable sleeve 26, which extends over and encircles the end of stub 24 and is attached thereto by a set-screw 27. The sleeve is also held onto the shaft 12 by a set-screw 28 and is keyed thereto by a key 29. The hub 23 also has alateral longitudinal opening 30, as plainly seen at Fig. 6, adapted to receive the stud31, formed on sleeve 26, 'laterally of the main bore therein. The sleeve when its set-screws 27 and 28 are releasedis movable back from hub 23 a sufficient distance to carry the stud 31 out of opening 30 and also sufficient to clear the stub 24, so that it will be seen that if the set-screw 22 at the other end of the shaft 12 is released the shaft will be readily removable from the carriages 16 and 17. When the fly-frame is thus removed, the carriage-operating mechanism is also thrown out of service in some suitable way-as, for

instance, by detaching the crank 33, by which shaft 19 is rocked, from the device by which it is operated, substantially as described in :my said patent.

The fly-frame, consisting of the shaft 12 and the iiy-lingers 13, may now be transferred to the position indicated in dotted lines atFig. 1 and connected to other IOO reciprocating rack 36, substantially as in my said Patent No. 610,491, is provided With hubs having laterally-projecting portions 37 'and 38, fast on the shaft and adapted to detachably receive and support the shaft 12 of the fly-frame between them in much the same Way that the shaft is attached to the carriages of the reciprocating delivery that is to say, the projection 37 is adapted to receive one end of shaft 12 and to secure the same through the medium of set-screw 39, While the projection 38 is provided with a stub 40, adapted to` enter the sleeve 26 and to be secured thereto by screw 27, and with an opening` for the stud 31, carried by the sleeve, so that it Will be seen that the fly-shaft can be readily secured in the projections 37 and 38 Whenever it is desired to use the fly-delivery in the same manner it is secured to the carriages 16 and 17 and also that it can be detached from the projections 37 and 38 in the same manner as from the carriages. W'hen the reciprocating delivery is in use, the rack 36-is prevented from operating the shaft 34 in some suitable Way-as, for instance, in the manner set forth in said patent.

By thus making the fly-frame so it can be attached either` to the carriages of the reciprocating delivery or to the rock-shaft of the fly-delivery I am enabled to Wholly dispense With the separate carrier heretofore customarily employed With the carriages.

It will be noticed that the attachments de- .scribed are not only quickly made and released, but that they are so constructed as to require no adjustment of the fly-shaft and no changes in position of the parts to which it is secured.

The sheet may be held so as to slide off the iiy-frame When the latter is used as a reciprocating carrier and recedes or returns for another sheet in any suitable Way. I have not thought it necessary to illustrate the means 1 used for this purpose, as a desirable construction thereof is illustrated in I claim- 1. In a printing-press, mechanism for operating a fly-delivery and mechanism for operating a reciprocating delivery, in combination With a liyframe adapted to be readily attached to or detachable from either of said mechanisms, substantially as specified.

2. The printing-press wherein are combined a single iiy-frame, mechanism to which the frame can be attached and by which it is oscillated and caused to serve as a Iiy-delivery and other mechanism to which the frame can be attached and by which it is reciprocated and caused to serve as a reciprocating delivery, substantially as specified.

3. In a printing-press, mechanism for operating a fly-delivery, and mechanism for operating reciprocating delivery, each provided With means for coupling the shaft of the flyframe to them, in combination With a iiymy said patent.

yas specified.
